The actor talked about how he was often a target due to his weight but came up with a unique defence mechanism:

'If you're big at school, you're going to be a target. If you go to school and you're me, you go, ''Right, I'm just going to make myself a bigger target. My confidence, it will terrify them.''

This fearless confidence has now carried him to success which of course all started with lovable sit-com, Gavin and Stacey and has now rocketed him to conquering US late night TV with the Late Late Show.
